Amazon Seller Central API: Key Listing Attribute Updates Effective October 26th

Amazon is implementing significant updates to its Seller Central Product API (SP-API) concerning listing attribute usage and enumeration values. These changes, set to take effect on October 26, 2025, will impact how sellers create and edit product listings, particularly those with offers. Developers and sellers utilizing the Listings Items API and the JSON_LISTINGS_FEED are advised to prepare for these modifications to ensure continued compliance and efficient listing management.

Key Takeaways

• New required attributes must be provided when creating or editing listings with offers.
• Sellers can select more relevant enumeration values from updated dropdown lists.
• These changes apply to the Listings Items API and JSON_LISTINGS_FEED.
• Product-only listings and XSD/XML feed uploads are not affected.

Impacted Users and Functionality

This update directly affects both private and public developers who use the Listings Items API and the JSON_LISTINGS_FEED data format for managing product listings. Specifically, any process involving the creation or modification of products that have associated offers will be subject to these new requirements. It is important to note that listings solely for products without offers, as well as those managed through XSD/XML feed uploads, will remain unaffected by this particular change.

Required Actions for Sellers

To ensure a smooth transition, sellers and developers must adapt their listing creation and editing processes. The primary action required is to provide values for newly introduced mandatory attributes. When updating existing listings or creating new ones, sellers should consult the updated attribute specifications. Additionally, if the new enumeration values offered for certain attributes are a better fit for the products being sold, sellers are encouraged to utilize these updated options to enhance the accuracy and discoverability of their listings.
